Crustaceans
Usually considered as a subphylum, Crustaceans comprise a group of arthropods including crabs, crayfish, lobsters and shrimp. Most crustaceans are aquatic animals, though some are terrestrial, parasitic and barnacles. Crustaceans have a chitinous exoskeleton, segmented body, and paired jointed limbs.

Where is the largest lobster at in the world located?
The laragest lobster is the American lobster. It is found in the North Atlantic Ocean from Newfoundland in Canada to North Carolina in the United States. It likes rocky and sandy sea floors.
Do lobsters 5 pairs of tentacles?
Lobsters don't have tentacles :P But they do have five pairs of legs.
The primary defensive feature in lobsters would be their behavior - avoidance of predators; they hide in crags or bury themselves in silt, or otherwise hide. This is especially important after they shed. A mottling or other coloration effects help. When confronted, they can use their claws to attack, or implement a flight reflex called the caridoid escape reaction by compressing their tail (abdomen) to swim backwards. There are also social defence behaviors, where they can group to increase mutual safety.
How does the lobster help the economy?
The economic importance of lobster is tied to the food service industry, particularly seafood restaurants, for which lobsters are caught and harvested. Hence the economy is supported by concerns which equip suppliers, and that catch, process, or transport lobsters or lobster meat. Without human consumption of lobster they would have a negligible economic impact.
Commercial aquaculture operations are somewhat unprofitable owing to the slow growth of the species and the lobster tendency to cannibalism.
Is is safe to eat lobster that has been frozen for one year?
There seems to be lots of anecdotal evidence that lobster can be safely frozen and still taste good when frozen properly, for up to two years. The secret seems to be to keep air away from the meat, for example by vacuum sealing; this will not only prevent freezer burn but inhibit any oils from going rancid. Many recommend a salt-water rinse also since it seems the micro-organisms that make frozen fish smell fishier multiply more easily in fresh water; and that salt water can prevent meat from shrinking or becoming mushy. As always, be sure to inspect once thawed, cut away any meat that is suspect, and cook thoroughly.
Do crustaceans have locomotion?
Locomotion = movement.Crustaceans generally move using their legs, but some, like barnacle adults and species like Sacculina, are anchored in place.
According to Wikipedia: "Scud is a series of tactical ballistic missiles developed by the Soviet Union during the Cold War and exported widely to other countries. The term comes from the NATO reporting name SS-1 Scud which was attached to the missile by Western intelligence agencies. The Russian names for the missile are the R-11 (the first version), R-17 and R-300 Elbrus (later developments). The name Scud has been widely used to refer to these missiles and the wide variety of derivative variants developed in other countries based on the Soviet design." Here is the link to the article: http://en.wikipedia.org/wiki/Scud "The Scud-B, deployed on a mobile launcher, was the version most commonly used by the Iraqi army in the Gulf War 1991. It is a relatively inaccurate weapon due to its primitive guidance system." Link to this source: http://encyclopedia.farlex.com/Scud+missile
Why do lobster march in a line?
Studies have revealed a couple reasons lobsters march in a line; one is a significant reduce in drag in the liquid medium which has a payoff over the long distances they migrate. Another is for defense; when attacked the lead lobster turns around and they arrange in a defensive formation.
What animals are related to sea monkeys?
Sea monkeys are actually a type of brine shrimp, so they are most closely related to other crustaceans like shrimp, crabs, and lobsters. They are part of the class Branchiopoda, which includes various species of small aquatic crustaceans.
Why were the British soldiers called redcoats and lobsters?
Because their uniforms were red. Think of the royal navy in Pirates of the Caribbean. ^^
This is not necessarily the case.. I have lived in South East Texas near the gulf my entire life, and I can assure you, those can be crawdad holes (see first link below..which is a pic of a crawdad/crayfish/crawfish hole)..and they do not live in above ground water alone, but they also live in tunnels in areas near the coast and can even be found more north where they will tunnel in lower areas of your yard where it gets extra wet after a rain.
When I was younger, we would find a stick and wrap the end of it with a small piece of raw bacon (or we would tie a piece of string around the bacon) and stick it down the hole (if the hole is not too far down, you will hit water..this is where you stop lowering the bacon and wiggle it around a bit to attract the crawdad) then we would hold still..if we were lucky, the crawdad would grab on, and you could gently pull him up out of his hole!
**Note: NEVER stick your hand in a crawdad hole, as there could also be snakes and/or spiders there as well if the crawdad has abandoned it.
Usually the wetter the mound (if there has been no rain for awhile)..the fresher the hole, and the more sure you can be that there is indeed a crawdad there...they roll up the mounds from underground and push them up to the top. They usually burrow far enough down to live where there is underground water (which is why the mounds can be wet) Larger crawdads can make pretty tall mounds! Here are some great websites and pictures if you would like to learn more! :)
Lobster as a food type is regarded as a protein, as opposed to a carbohydrate or a fat, although the meat contains some of each to a degree; a restaurant would categorize it as "seafood" and present it on a menu alongside fish, shellfish, shrimp, etc.
Does a lobster move backwards?
As with all pronograde organisms with sensory organs located on the head, the normal motion of a lobster is notionally "forward" in that direction; but in many crustaceans like shrimp, lobster, crayfish, there exists a "caridoid escape reaction" by which they can achieve a burst of speed by abdominal muscle compression, used to escape predators, in effect flipping their tail to swim suddenly backwards.
How many babies does a crayfish have?
This depends on the species and size of the crayfish, but a few hundred per spawn is not uncommon for a mature female
When is the best time of year to find seashells?
The most variety of shells can be found late winter, early spring. late December through February.
Yes - you can.
I gutted and filleted one i caught yesterday slow fried it in oil and butter skin side down with salt pepper garlic and chilies it was delicious!
A scud is a herbivore because it only eats plants. Scuds are tiny crustaceans, that are close relatives of crayfish and water fleas.
What is the growing process of a lobster?
A lobsters live starts as an egg which hatches and is released as larvae by the female, where they drift to the surface in their planktonic phase, which lasts for a couple months. At this stage they are only a few millimeters across, and do not resemble adults, but look more like small shrimp. These grow and moult a few times, the third time being a metamorphasis where they resemble an adult, and about a half inch across, where they begin to drift to the sea bottom (the benthic phase). Initially they hide all the time, as they continue to grow and moult they begin to venture out more to forage.
It is not known exactly how old they can get and it's possible they do not have an age limit; the largest lobster on record was about one meter in length and weighed in around 45 pounds.
Is lobster an analogy for a crab?
In a limited sense. One definition of analogy is an agreement in details or features, which lobsters and crabs share; but, the words crab and lobster in common usage have distinct and separate meanings; a crab is not a type of lobster nor is a lobster a kind of crab. Probably a matter of opinion but it would seem to stretch credibilty to take license for direct substitution of one for the other in literature. It might be better to say they have analgous characteristics or analogous structures. The term analogy is used in evolutionary biology do describe a common descent: indeed, crabs and lobsters do share a significant portion of their taxonomy, for example, those categories which describe marine crustaceans.
